Vedclass · Answer

(D) The extraction of $Ag$ from its sulphide ore (argentite,$Ag_2S$) involves the formation of the dicyanoargentate$(I)$ complex,$[Ag(CN)_2]^-$. The removal of unreacted silver bromide $(AgBr)$ from a photographic plate (fixing process) involves the formation of the thiosulphatoargentate$(I)$ complex,$[Ag(S_2O_3)_2]^{3-}$. Therefore,the complexes involved are $[Ag(CN)_2]^-$ and $[Ag(S_2O_3)_2]^{3-}$ respectively.

Extraction of $Ag$ from sulphide ore and removal of unreacted silver from photographic plate involve complexes are respectively
